The "three-point seven-point pipe" of rice is very important for transplanting. This year's Wujiang rice transplanter has a tight schedule and heavy tasks. It is necessary to earnestly implement timely planting and ensure the quality and quantity of the rice transplanting tasks.
First, strengthen the management of Putian, cultivate standard seedlings:
1, timely removal of film hardening seedlings, non-woven cover generally 8-10 days, after the harvest of wheat dishes, it is timely to remove the film refining seedlings, promote seedlings robust.
2, appropriate fertilizer to promote strong, remove the film after the appropriate Tiantian fertilizer, apply urea 5-7.5 kg per mu (bed soil with strong agent or matrix, generally do not make up fat).
3. Appropriate water slurry management. After sowing, paddy fields are kept full of gutters. Before the three-leaf stage, the front seesaw is kept moist. During the three-leaf stage, a shallow water layer is built, and the water is drained 2-3 days before the machine is inserted to ensure that the bed soil is suitable for drying.
4, timely prevention of pests and diseases, the general use of 2 times of paddy fields, the first time after film removal 1-2 days, the second machine before the insertion of 1-2 days, focus on good prevention of planthoppers, rice, etc. Pests.
Second, timely rice machine inserted to ensure planting quality:
1, to return straw, full base fertilizer. After the harvest, the total amount of straw shall be returned to the field, and 0-35 kilograms of wheat flour, or 20 kilograms of high-concentration compound fertilizer and 15 kilograms of ammonium bicarbonate.
2, to timely plough, improve quality. After the harvest, we must promptly plough and ensure that the ploughing task is completed before June 10th. At the same time, we must improve the quality of the whole field. Straw should be buried deeply and the field should be leveled.
3, timely harvest, ensure the season. Master 15-18 days of age, 15 days to start machine insertion, 18 days machine end of the plug to prevent the emergence of earthworms and other fields. Suitable for transplanting June 10-20, but not later than June 25.
4, to ensure the density, improve quality. Machine inserted when the spacing of 12 cm, acres planted 17,000 points, 4 seedlings per hole, the basic seedlings 6 - 70,000, while paying attention to shallow interpolation, timely fill seedlings, reduce missing trees. After the machine is inserted, fill in shallow water in time to prevent the water depth from causing drifting.
Third, strengthen a kind of management, promote early pre-term:
1. It is necessary to timely apply the first herbicide and tiller fertilizer. After the machine is inserted for 4-5 days, 12.5 kilograms of urea per mu, plus 30% of direct-airing 100 grams, mix and spread, and keep water for 4-5 days to prevent grass damage. Pay attention to the timely application according to the progress of machine insertion.
2, to start dehydration and field exposure. After applying the tiller and herbicide and keeping the water for 4-5 days, it is necessary to timely dehydrate the exposed fields, precipitate the sludge, promote the growth of new roots, promote the early emergence of early tillers, and generally dehydrate the fields for 4-5 days. In particular, the field where straw is returned to the fields is more important for dehydration and ventilation, and it is necessary to prevent field rottenness, weak seedlings, and black roots, resulting in failure to produce a stiff seedling.
